DeSOTO, Texas -- The second annual Rivals Underclassmen Challenge presented by Under Armour took place Sunday in Texas and several players turned heads with their performances. Rivals.com Southeast recruiting analyst Woody Wommack breaks down the top performers at the running back position.

Williams has early offers from Georgia, North Carolina and N.C. State and he showed why on Sunday. Even though he's built to be an every-down back, he showed a nice burst, especially when he turned up the field on pass plays. Williams isn't the fastest back in the world, but has the quickness and the moves to be a very effective back.

Warren is the son of the former NFL running back with the same name and he looked a lot like his father on Sunday. At 6-foot-2, 215 pounds, Warren already has a college-ready body, with good speed to go along with it. For a guy his size, he really moves down the field and has the skills to be a weapon out of the backfield as well. On several occasions, he blew away linebackers in one-on-one pass drills.

Johnson had one of the highlights of the day when he planted his foot into the ground on a route and put the linebacker defending him into the spin cycle before streaking down field for an open catch. He has great speed and looks like a home run threat at the running back position. It's no wonder Alabama, Auburn and LSU have already offered.

Williams is a running back but during pass drills on Sunday, he looked like he could play slot receiver. He's a natural pass catcher and he knows how adjust to the ball in the air, a rare skill for a running back. He also keeps his pad level low, something that will pay dividends when he's carrying the ball behind an offensive line on Fridays and Saturdays.

White is a big-bodied running back but he moves very well in space. He also has great speed for his size, and looks like he could have elite potential. He's only a rising sophomore, but LSU has already offered. It could be difficult for him to stay at the position if he keeps growing, but right now it looks like he has a college-ready body.

Gallaspy has power back written all over him and he has the body to take the pounding of an every down back. On Sunday, he also showed good hands, more than holding his own during one-on-ones. He already has four ACC offers, including North Carolina and N.C. State and several other schools are likely to follow.

Thomas is another big-bodied back, but he can really move when he gets out in space. He has great feet and he doesn't waste any movements, a key attribute for a running back. He also did well in the passing game, making some good grabs against some solid linebackers.

Speights flashed terrific speed on Sunday, blowing away linebackers on wheel routes during one-on-ones. He's an all-purpose back and looks like he would be a perfect fit in a spread offers. So far Arizona is the only school to offer, but Speights should have several more before it's all said and done.

Jones isn't the tallest back, but he's built solidly and looks the part of a solid prospect. When he puts his foot in the ground he can make some terrific cuts, allowing him to shake defenders. He doesn't have any offers yet, but schools would be wise to keep on him going forward.

Ozigbo has a solid build, but he can run when he gets out in space. For a player who weighs more than 200 pounds at the running back position, he's really athletic, making him a threat in the passing game as well as on the ground.
